To all whom it may concern:

Be it lrnovvn that 1, PETER Scnuzoon, a citizen of the United States, residing at Pekin, in the county of Tazewell and State of lllinois, have invented certainnew and useful :improrements in Washingg hlachines, of which the following is a specification.

My invention relates to Washing machines.

My invention has special reference to a type known as pounder Washing machines.

The object of my invention is to provide mechanical means for forcing air and Water through the body of the clothing being Washed; to apply plunger devices possessing vacuum or suction action in such a manner as to render such action efilicient to the highest degree; to means for effecting the movement of plunger members to cause the clothing being Washed to be moved progressively about the interior of a container or receptacle.

My inrention consists in the association of a plurality of plunger members possessing structural capability for vacuum ac tion in a relation to impinge the clothing in a washing receptacle, each at different intermitting periods successively and continuously until a washing is finished, and further consists of detail parts and combinations hereinafter more particularly pointed out.

Referring to the drawings-l igure l is a top plan View of my invention applied to a washing receptacle; Fig. 2 is a side elevation of a Washing machine body showing my invention applied; Fig. 3 is a sectional vieu taken on the line oo of Fig. 1, looking); in the direction of pointing of the arrow, and showing one of the plunger members in diil'erent positions; Fig. l is a top View of the receptacle with apart broken away to show the relative arrange-- ment oi. vacuum plunger members; and Fig. is a perspective view showing plunger members and driving connections therefor.

I am aware that vacuum actingplunger members have heretofore been variously plied. that is I know that hand plungermembers are common in the art, andam also aware that both single and plural members have been employed in connection with suitable gear and power connections to cause said members to reciprocate in the washing receptacle, but am not aware of vacuum acting plunger members oi this character being; arranged in the manner herein disclosed, and gear and supporting connection employed to cause the same to operate in a manner to gradually turn the clothing about in the receptacle.

Referring to the drawings, 2 is a tub of a.

common type and 3 are supporting members or legs.

l is a stationary top member and 5 a lid hinged to top member 4 as at 6 and adapted to swing to and from closed positions.

7 is a hasp or fastener of a well known type, shown diagramatically in the drawings, to bind the lid to the tub.

Referring to Figs. 3, at and 5, 10, 11 and 12 are cone shaped members of a common type adapted to serve as-plungers in connection with the washing of clothes and capable of certain vacuum or suction action under proper manipulation when used to effect cleansing purposes. Each of the said conical shaped members is connected to plunger members as 13., i l and 15 by means of cast members as 16, or in any suitable manner that may be desired. 17 are respectively, looped members connecting in a pivotal manner with lugs 18 on cast member 16, and with eye members 19 depending from the under surface of the lid or cover Pivoted link members 17 are preferably spaced apart at their point of connection with the eye members 19 on the lid for the purpose of a brace against lateral movement of conical members 10, 11 and 12.

The conical members 10. 11 and 1'2 are designed to be disposed Within the Washins" receptacle or tub in spaced relation at substantially equal distances apart and in an arrangement on progressive circular line about the interior thereof, the aim being to present, through members 10, 11 and 12 plural active agents successively operative to eli'ect the purposes herein contemplated. To effect this desired operation of the plung'ermembers (comprising conical members 10 and plunger members 13) l have provided an operating shaft 20 thht is disposed upon lid 5 and secured in boxings 21 and respect irely connected with cast members 253 and 3+. Shaft 20 is formed with a crank member 25 connected by strap member 26 "with plunger member 13. whereby the turning of shalt 20 Will effect a substantially vertical action of plunger memberF-lrl and the conical member 10 connected therewith. To one extremity of shaft 20 is v fixed a beveled gear 27 which meshes with bevel gears 28 and 29 disposed at each side thereof and of shaft '20, said bevel gears being fixed respectively to stub shafts -30 and 31, the latter being journaled in .boxings 32. and 33 supported in connection with cast bracket member 2i. To the similar vertical reciprocating action to that of plunger member 13 is imparted to plunger members 14 and 15.

In carrying out the plan of my invention, 1 have designed a working relation ofthe parts to effect an alternate engagement respectively of conical members 10,11 and 12 with the body of clothing within the receptacle, and to this end I have so disposed the connection of plunger members 13, 14 and 15 with their supporting and driving connections as to step and time their action relatively to effect the movement above indicated. v

The action of the plunger members effected by the connection respectively at their outer ends with the crank and eccentric members, and with the tub through and by means of member 17, will cause them to reciprocate bodily horizontally some distance and to provide for this reciprocation, I have provided the slotted openings in thelid or cover 5 as at 36, 37 and 38.

' T have shown in diagrammatic manner-a connection for operating the devices of my invention from a motor X. The connection embraces a gear 39 fixed to shaft 20, a

reducing gear 40 on a stub shaft 41, the latter suitably supported in connection with the Washing machine body. This connection also includes drive pulley wheels 42 and 43 respectively connected with stub shaft 41 and the motorshaft.

The operation of the device disclosed, for the purpose of performing a washing, would include the filling of the tub with. water to substantially the point indicated by dotted line 0-0 in Fig. 3, the placing of the clothingwithin the receptacle and the operation of the devices from some source of power, as

by hand or motor.

Describing the operation from a motor connection, shaft 20 will be driven continuously in one direction, and similarly the action of crank 25 and of gear wheels 28 and 29 will be in a continuous direction. The proper relative connection of plunger members 13, 14-. and 15 respectively with crank arm 25 and gear wheels 28 and 29 will, when shaft 20 is rotated, cause the plunger members, including the conical parts 10, 11 and 12, to be moved successively to and from action upon the clothing in the manner shown in the several positions of said parts in Fig. 3, so that each conical member 10, 11 and 12 will successively and at different times be brought into contact with the clothes, and each in turn will be brought to a position above the surface of the water. This action of the plunger members will serve to take in, a supply of air as each conical member passes above the surface of the water, and to carry the same to a position of coiiperation in connection with the clothing that will eifect a forcing of the air through the clothing and water. The certainty of this action is caused by the manner of connecting the brace members 17 to the plungers 13, 14, 15 which, it will be noted, are pivoted to the plungers between their ends and to the top aof the tub at 19,the latter pivotal points being in a horizontal plane ,or substantially so with the highest point reached by the points of connection to the plungers so that when the plungers descend, they are caused to'swing in. such manner that the conical members 10, 11 and 12 press squarely on the clothes and move them positively in a forward direction. These forward thrusts following successively one after the other push the clothes in a circular path around the tub and continually presents new surfaces to be acted on by he plungers. Also the movement respectively of conical members 10, 11 and 12 from the extreme upper position of said members to the extreme lower position, as disclosed in Fig. 3, will actupon the clothing within the receptacle to advance the body therein in a progressive manner, thus serving to position the clothingfor a. different point of contact or enagement, at each contact of the respective conical members, thus serving a. very valuable function and purpose in the manner of accelerating the Washing action and uniformity therein.

1 have shown herein one form of embodiment of my invention, but parts and mechanisms may be variously arranged, formed and operated to effect a plural successive impingement of the clothing progressively about a container receptacle, and coincidentally efi'ecting progressive movement of the body of'clothing, therefore I do not confine myself to the parts and arrangement of parts herein disclosed, but claim all forms of embodiment of parts to effect the purposes herein.

What I claim is: 4
